Dual column surgical support system

摘要

A surgical patient support includes a foundation frame, a support top, and a brake system. The foundation frame includes a first column and a second column. The support top is coupled to the first column and the second column for rotation about a top axis extending along the length of the support top.

主权项

1. A patient support apparatus comprising
a caster including a stem, a wheel coupled to the stem to rotate about a wheel axis relative to the stem, and a braking element movable from a disengaged position allowing rotation of the wheel relative to the stem to an engaged position blocking the wheel from rotation relative to the stem, a brake drive including a mount and a linear actuator coupled to the mount, the linear actuator to move from a retracted position to an extended position relative to the mount, and a linkage coupled to the braking element of the caster and to the linear actuator of the brake drive, the linkage configured to transfer motion of the linear actuator from the retracted position to the extended position to the braking element to move the braking element from the disengaged position to the engaged position, the linkage further configured to selectively move the braking element from the engaged position to the disengaged position while the linear actuator is in the extended position so that a user can free the wheel of the caster to rotate even if the actuator is stuck in the extended position, wherein the linkage includes a shaft coupled to the mount to slide relative to the mount and a release assembly coupled to the linear actuator, the release assembly configured to couple the shaft to the linear actuator so that the shaft slides along a linear path relative to the mount in response to movement of the linear actuator from the retracted position to the extended position and to selectively release the shaft from the linear actuator when the linear actuator is in the extended position.
